Because these tests are so expensive, I usually can't see the benefit over a Prostate Health Index (PHI) test. PHI is FDA-approved and covered by insurance (it only costs $125 anyway).
Here's a study about
There's another (urine) test called SelectMDx that isn't PSA based. The cost is around $300. It's accuracy seems to be excellent:/mdxhealth.com/selectmdx-prostate-cancer
Another urine test that is not PSA based is called "ExoDx Prostate Intelliscore." /jamanetwork.com/journals/jamaoncology/fullarticle/2506709
I think you might be able to get it for free on a clinical trial if one of the
locations is near you:/clinicaltrials.gov/ct2/show/NCT03031418
The advantage for you of a non-PSA-based test is because you have known BPH and prostatitis, which will affect any PSA-based test to some degree. PCA3 is a urine test, but is only FDA approved after a first biopsy. An MRI, likewise, should be reserved for a second or confirmatory biopsy. Neither is used to determine whom to biopsy in the first place.
